Mike Starr, the former Alice in Chains bassist and, of late, former patient on "Celebrity Rehab," is dead at 44.

TMZ reports that authorities found the musician's body at a Salt Lake City, Utah home on Tuesday. His father told the site that his son's death is "a terrible shock and tragedy."

Last month, the 44 year-old was arrested for felony possession of a controlled substance.

Week by week, Starr battled his demons on the VH1 reality show and even appeared this past season as an alumnus as an inspiration to new patients.

Dr. Drew Pinsky, the addiction medicine specialist who oversees the patients on 'Rehab,' tweeted his respects. "Devastating to hear of Mike Starr succumbing to his illness. So very sad. Our prayers are with his family."

From 1987-1993, Starr played bass for the grunge band but was replaced by Mike Inez in 1993. In 1994, Starr was sentenced to 90 days in jail for stealing a piece of luggage at the Houston Intercontinental Airport.

The band's frontman Layne Staley was found dead of a heroin overdose in a Seattle apartment in April 2002. Starr said on 'Rehab' that he may have been the last person possibly to see Stanley alive. At the time, Starr was battling his own drug demons.

"I wish I hadn't been high on benzodiazepine. I wouldn't have just walked out the door," Starr told Dr. Drew on the TV show. He went on to say that he didn't want to end up like his former bandmate.

Starr appeared on 'Rehab' with Tom Sizemore, Heidi Fleiss, Mackenzie Phillips, Dennis Rodman, Mindy McCready and Kari Ann Peniche. He also appeared on VH1's "Sober House.
